CLASP FoR ALBUMS.

SPECIFICATION forming part of Letters Patent No. 251,901, dated January 3, 1882. Application filed September 28, 1881. (ModeL) Patented in Germany May 11, 1881.

To all whom it may concern:

Be it knownthat I, HERRMAN LANDSBERG, of Offenbach-onthe-Main, Germany, have invented a new and useful Improvementin Clasp- Locks for Albums and other Purposes, of which the following is a full, clear, and exact description.

In the accompanying drawings, Figure 1 is a perspective view of my improvement, shown as applied to an album-clasp. Fig. 2 is a sectional elevation of the same, taken through the line xx,Fig. 1. Fig. 3 is a side view of the same, the clasp-loop being removed. Fig. 4 is a plan view of the same, shown as unlocked.

Similar letters of reference indicate corresponding parts. I

The object of this invention is to promote security in fastenings for album-clasps and other purposes.

The invention consists in a clasp-lock for albums and other purposes, constructed with an outer stationary tube and an inner movable tube having a key-hole plate or button attached to its upper end. Both tubes are slotted to receive the lug of a spring-pressed ring placed upon a stationary pivot concentric with the two tubes. The lock is fastened and unfastened by pressing the ring inward to release its lug with a key, and then turning the'key-hole plate with the said key, as will he hereinafter fully described.

A and B are the plates of an album-clasp, which are so formed or looped as to fit upon the forward edges of the book-cover and overlap the outer and inner sides of the said edges.

The looped plates AB are secured to the bookcover by rivets or clinched nails, so that the connection will be firm and strong.

Upon theend parts of the bend of the plate A are formed twospherical knobs, O, which are slotted longitudinally and at right angles with the length of the said plate A to receive the circular heads D formed upon the ends of the wire E, and which are pivoted to the said slotted knobs by rivets, thus forming neat, strong, and durable hinges. The wireE is bent into triangular or V form, and the loop thus formed is passed over and rests upon a short tube, F, lormed upon or attached to the center of the bend of the plate B.

Upon the open outer end of the tube F rests a plate, G, upon the under side of which isv formed, or to it is attached, ashort tube, H, of such a size and length as to fit into .the tube F. To the bend of the plate B is attached a pin, I, to serve as a pivot to the key 0. The pivot I is concentric with the tubes F H, and is made of such a length that its outer end will be about flush with the outer surface of the plate G, the said outer end passing into the circular larger endot' the key-hole formed in the said plate G.

Upon the pivot l and within the tube H is placed a ring, J, which .is pressed outward by a spiral spring, K, placed upon the pivot I at the inner side of the said ring J.

Upon one side of the ring J is formed, or to it is attached, a lug or pin, L, which projects through a short longitudinal slot, M, in the side of the tube H and into a slot, N, in the side of tube F. The slot N passes about haltway around thetube F and has a notch at each end in the direction of the plate G. The plate is made of such a shape and size that when turnedin one direction it will fit into the bend of the loop E, as shown in Fig. 4, and when turned half-way around its side parts or wings will overlap the arms of the loop E, as shown in Figs. 1 and 2, and fasten the said loop in place.

In using the lock the key 0 is passed into the key-hole in the plate G, so as to restagainst the ring J, and is then pressed inward, pressing the said ring J inward and pressing the lug L out of the notch of the slot N and into the body of the said slot, the lug L striking against the edge of the said slot N and preventing the ring J and key 0 from passing so far inward as to carry the guard of the key 0 through the plate G. The key 0 is then turned one-half a revolution and is then withdrawn.

The turning of the key 0 turns the plate G and tube H, and the tube H, bearing against the lug L, turns the tube F and carries the said lug through the slot N from end to end. The withdrawal of the key 0 allows the spring K to force the lug L into the notch at the said other end of the slot N and fasten the plate G in place until it is again operated by the key.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. In a clasp-lock for albums, the combination of the tube F and plate B with the plate G and inner tube, H, whereby the tube F and plate G operate as a knob to hold the hinged loop E when unlocked, substantially as shown and described.

2. A clasp-lock for albums and other purposesconstrueted substantially as herein shown and described, and consisting of the stationary slotted tube F, the plate G, carnying the slotted inner tube, H, the pivot I, the ring J, having the lug L, and the spiral spring K, as set forth.

3. In a clasp-lock foflalbums and other purposes, the combination, with the looped plate B and the hinged loop E, of the stationary slotted tube F, the plate G, having slotted tube H, the pivot I, the ring J, having lug L, and the spiral spring K, substantially as herein shown and described, whereby the hinged loop and-the looped plate can be readily fastened together and released, as set forth.
